I stand by my comment from before:
The person who wrote that paper doesn't understand the basics of the field that he's talking about.
For example (quote from the other thread): "Consa gives an analogy wherein Indian mathematician Srinivasa Ramanujan has claimed that the sum of all positive integers is not infinite, but is instead -1/12. It’s wrong, it’s absurd, but renormalization has now been accepted, and is even sold as a virtue."
One when performs zeta function regularization, one gets -1/12. This isn't some mystery; it's a perfectly reasonable thing to do. Analytic continuation has been understood since the 1800s.

Also, the claim that Karplus and Kroll committed "fraud" is basically libel, as can be seen by reading the complete account. The worst one can say is that people didn't publish full details of calculations due to page limitations or laziness, but this is hardly a special feature of QED. For instance, Onsager famously solved the 2-d Ising model exactly in 1944 but never provided details in print, just the final solution.
And he is completely missing one of the biggest drivers in modern physics: you have basically an army of researchers trying desperately to find something, anything that is provably wrong with QFT. Because we know it's not the final theory, something is missing, and finding concrete errors might very well show us the way to a better theory.
If, as the author claims, some original Feynmann diagram calculations are "kept secret" and actually wrong, all it takes is one postdoc somewhere to actually redo the calculations and show the error for all the world. That's a career defining paper right there, something that would make you famous in the community. If people thought there was even a 0.01% chance that was the case, they would be chasing it hard.
the author sends obsessed with the fact sooner people didn't shows their work, meaning everything collapses -- but people since then have got the same result but different calculations.
everyone in the field knows QED is full of weird Martha's, and isn't the " answer to everything", but no one has a better answer, and it does produce results which line up with reality.
yes, I agree there paper is nonsense.

“I must say that I am very dissatisfied with the situation because this so-called ’good theory’ does involve neglecting infinities which appear in its equations, ignoring them in an arbitrary way. This is just not sensible mathematics. Sensible mathematics involves disregarding a quantity when it is small – not neglecting it just because it is infinitely great and you do not want it!. ”
"The shell game that we play is technically called ’renormalization’. But no matter how clever the word, it is still what I would call a dippy process! Having to resort to such hocus-pocus has prevented us from proving that the theory of quantum electrodynamics is mathematically self-consistent. It’s surprising that the theory still hasn’t been proved self-consistent one way or the other by now; I suspect that renormalization is not mathematically legitimate.”One good article that explains this shift (in the context of a debate in the philosophy of physics) is here: http://philsci-archive.pitt.edu/8890/.
It's a conspiracy theory with sparkle of equations.

The paper claims there are problems already with g-factor, could anybody explain why its objections are not valid?

(I explained why the narrative is not valid in another comment).
Consa brings concrete arguments regarding g-factor, I still haven't seen any concrete explanation, only saying that it is fringe science because of criticism of mainstream ... but he quotes mainstream papers.
It isn’t the answer to everything because the electromagnetic force isn’t the only fundamental interaction and we don’t have a theory of everything. But QED explains one of the fundamental interactions far better than the paper tries to paint it. See The Relativity of Wrong by Isaac Asimov.
I think the linked article agrees with you that QED is well tested.
Their point (IMO) is that there is one free parameter in QED that was not highlighted as such. There is nothing wrong in free parameters, we know very little of the universe. As far I know there are free parameters in the standard model, but it is clearly stated as such so there is no problem.
